Write Your First Code

1. Create a New Project

2. Write Your Code

  • Make sure the main source file (e.g., main.c) is opened
  • Replace content from main.c file with the simple code example below, which showcases blinking an LED
/**
* If hardware without pin `MIKROBUS_1_CS` is used,
* make sure to define adequate pin.
*/
#ifndef MIKROBUS_1_CS
#define MIKROBUS_1_CS NC
#endif

/* LED pin. */
#define LED MIKROBUS_1_CS

/* Digital output driver context structure. */
static digital_out_t output_pin;

int main(void) {
 /* Set pin LED as digital output. */
 digital_out_init( &output_pin, LED );

 /* Infinite loop. */
 while ( 1 ) {
   /* Toggle pin digital state. */
   digital_out_toggle( &output_pin );
   /* 1 second delay. */
   Delay_1sec();
 }

 return 0;
}

Let's break down and explain the code example that showcases a simple LED blinking using the mikroSDK 2.0 GPIO driver library.

Project Overview

  • The provided code demonstrates how to create a simple LED blinking application using the mikroSDK 2.0 framework

  • The example toggles a specified LED pin on a development board

  • Code Explanation

  • Library Inclusions

#include "MikroSDK.Driver.GPIO.Out"
#include "MikroSDK.Board"

This code includes the necessary libraries:

  • **MikroSDK.Driver.GPIO.Out**: The GPIO driver library for handling digital output

  • **MikroSDK.Board**: The board definition library

  • Pin Definition

// If hardware without pin `MIKROBUS_1_CS` is used,
// make sure to define adequate pin.
#ifndef MIKROBUS_1_CS
#define MIKROBUS_1_CS NC
#endif

Defines the MIKROBUS_1_CS pin if it is not already defined.

If your hardware doesn't have this specific pin, it defaults to NC (not connected).

  • LED Pin Definition
/* LED pin. */
#define LED MIKROBUS_1_CS

The LED pin is defined as MIKROBUS_1_CS.

  • Digital Output Context
/* Digital output driver context structure. */
static digital_out_t output_pin;

A context structure output_pin for the digital output driver is defined.

  • Main Function
int main(void) {

/* Set pin LED as digital output. */
digital_out_init( &output_pin, LED );

/* Infinite loop. */

while ( 1 ) {

  /* Toggle pin digital state. */
  digital_out_toggle( &output_pin );

  /* 1 second delay. */
  Delay_1sec();
  }

 return 0;
}

The entry point of the program. Initializes the LED pin as a digital output using digital_out_init. Continuously toggles the state of the LED pin and waits for 1 second using Delay_1sec(). This creates the blinking effect. This code example provides a simple way to blink an LED using mikroSDK 2.0's GPIO driver library.

It sets up the necessary hardware configurations, initializes the LED pin as a digital output, and toggles the LED state in an infinite loop with a delay of 1 second.

By following the steps to configure the Library Manager, you can ensure all necessary dependencies are included for successful compilation and execution.

For additional resources, check out:

3. Configure Library Manager

After copying the previous code into main.c file of the Application type of a NECTO Studio project, you need to configure the necessary libraries in the Library Manager:

  • Open Library Manager

    • Navigate to the Library Manager in NECTO Studio.

  • Check Required Libraries

    • Make sure to check Board and Driver.GPIO.Out libraries
